A fluid end for a reciprocating pump assembly includes a fluid end body defining an access opening having access opening threads formed on an inner surface thereof and extending between an inner threaded portion and an outer threaded portion. A blunt start is formed at the outer threaded portion of the access opening threads. The fluid end also includes a retainer nut having retainer nut threads formed on an outer surface of the retainer nut. To install the retainer nut in the fluid end, a first threaded portion of the retainer nut threads is configured to engage with the access opening threads before the second threaded portion. When the retainer nut is in a fully engaged position in the access opening, a second threaded portion of the retainer nut threads is offset from the blunt start of the access opening threads to define a circumferential offset distance therebetween.

System and method for reduced thread stress for buttress style threads used in frac pump fluid ends

A wear-resistant hydraulic fracturing pump valve seat including a body of the valve seat extending radially away from a central axis. The valve seat includes a first top surface configured to form a metal seal with a first bottom surface of a valve head, the first bottom surface positioned closest to a base of the valve head. The valve seat further includes a valve seat step positioned directly adjacent and above the first top surface and a second top surface disposed directly adjacent to and above the valve seat step. The second top surface is configured to form a second metal seal with a second bottom surface of the valve head. The valve seat step is configured to place the first top surface and the second top surface in different parallel planes from each other.

Wear-resistant hydraulic fracturing pump valves

A fluid pump may include a fluid chamber, a plunger configured to reciprocate within the fluid chamber, and a valve system including multiple valves. The multiple valves each may be configured to control fluid flow into the fluid chamber or each may be configured to control fluid flow out from the fluid chamber.

Multiple-valve system for a fluid pump

A system for monitoring a piece of hydraulic fracturing equipment such as a positive displacement pump. The system includes a plurality of sensors configured to detect conditions of the hydraulic fracturing pump and a processor that is communicatively coupled to the plurality of sensors and configured to analyze data received from the plurality of sensors. The processor is also configured to predict faults in the hydraulic fracturing pump based on the data analysis. The system also includes a communication interface that is configured for transmitting predicted fault data to one or more devices.

A valve seat for a valve assembly for a high-pressure fluid pump is disclosed. The valve assembly includes a valve body, and a valve seat fabricated of a first material. The valve seat has a generally a tubular body having an annular collar having an outer diameter surface extending beyond the outer diameter surface of the tubular body, and an annular insert fabricated of a second material more durable than the first material and affixed to form an inner diameter surface of the collar, the insert forming an annular sealing surface against which the valve body abuts when in a closed position. The insert forms an annular ledge edge at its inner diameter surface that is offset from the inner diameter surface of the tubular body to form an annular chamfered edge.

Valve seat with ceramic insert

The present disclosure relates, to a wear-resistant hydraulic fracturing pump valve for use in a valve housing, the wear-resistant hydraulic fracturing pump valve comprising: (a) a valve head extending radially from a central axis, the valve head comprising: (i) a first bottom surface comprising a metal and positioned closest to a base of the valve head, wherein the first bottom surface is configured to form a metal seal with a top surface of a valve seat; and (ii) a first annular groove positioned directly adjacent and above the first bottom surface; and (b) a first wear-resistant pump valve gasket configured to mount inside the first annular groove and to form a valve gasket seal with the top surface of the valve seat.

A valve member for an inlet or outlet valve assembly of a reciprocating pump assembly includes a valve body and a seal member. The valve body comprises a first body surface and a second body surface that extend circumferentially about the valve body. The valve body defines a body axis and an annular cavity. The seal member is positioned at least partially within the annular cavity of the valve body such that an outer seal portion of the seal member extends between the first body surface and the second body surface of the valve body. The outer seal portion of the seal member comprises a first seal surface and a second seal surface. The first body surface, the first seal surface, and the second seal surface extend at different angles relative to the body axis.
